If you just want to color based on the rising/falling conditions w/o having to code anything, you can use THIS TOOL referenced by @Sylvester17. The tool is HERE.

You can color any indicator with plots with it.

I watched the video and see how it works. The problem is I want to use it on a higher time frame so it is better if I could have the code in the Linear Regression Intercept?

Did you configure the input?

Watch that video at the download link, he explains how to configure the input in the first 30 seconds or so. That would be the easiest way to get an understanding.

I watched the video and see how it works. The problem is I want to use it on a 500 tick chart using a 1000 tick data series on the same chart so it is better if I could have the code in the Linear Regression Intercept?

So you want a 1000 tic LRI displayed ONTO a 500 tic chart?

Yes, in panel 1. I just add two data series to the chart, add them both to Panel 1 and change the input series on the LRI..

This can be done also with that indicator....

I do not mean to discourage you wanting to code it, I was just suggesting this as a way to not have to code anything, which if that is the case you can do that also.

But I figured Id point it out.

But if you want to do it, you can add a second data series to your chart of 1K tics like I have. Then apply the plot to that second series. You can then shrink the bottom panel where you can't see it anymore(2nd pic).

Both averages are shown. The orange is the standard one on 14 periods. The colored one is based on the 1K tic chart of 14 periods with the rising/falling conditions
